Problem texturing a complex model like the interlaced leaves of a palm tree
Maybe you can try this neat selection trick : just click on the ending vertex of a leaf, and do "CTRL +" repeatedly to increment your selection. "CTRL -" to deselect.

Another trick that you can also try is to hover over a leaf, and hit L on the keyboard. This will select the actual object as a whole (provided it is a separate mesh). You can hide it by pressing H, and reactivate it with ALT+H.

Hope it helped, and welcome aboard !
